      <documentation>XML encoded GetCapabilities operation response. This
      document provides clients with service metadata about a specific service
      instance, usually including metadata about the tightly-coupled data
      served. If the server does not implement the updateSequence parameter,
      the server shall always return the complete Capabilities document,
      without the updateSequence parameter. When the server implements the
      updateSequence parameter and the GetCapabilities operation request
      included the updateSequence parameter with the current value, the server
      shall return this element with only the "version" and "updateSequence"
      attributes. Otherwise, all optional elements shall be included or not
      depending on the actual value of the Contents parameter in the
      GetCapabilities operation request. This base type shall be extended by
      each specific OWS to include the additional contents
      needed.</documentation>
